Abstract

The survival of the Bacillus cultures on the seeds of the maize was tried in different combinations. One ml inoculum with one ml adhesive combination or sterile water showed better results followed by 1.5 ml inoculum with 0.5 ml adhesive or sterile water. In 1.5 ml inoculum and 0.5 ml adhesive combination, adherence and survival population of phosphobacterial cells were maximum (6.5×10⁵ cfu/seed) for the treatment of sporulated inoculum with rice gruel.

Keywords

Abstract

Zinc deficiency was created in maize seedlings in the sand culture and deficiency was rectified with the addition of insoluble zinc sources and G. diazotrophicus. The basic strategy behind this approach is decreasing the pH and making zinc soluble and as a consequence, the available zinc will get increased in the soil system. Since lowering of soil pH to 5 or below increases the Zn solubility. The plant growth, chlorophyll content and plant zinc content were found to be enhanced due to inoculation of G. diazotrophicus with insoluble zinc compounds.
